Phillip Tarrant 5e3a70f837 Fix schedule management and update documentation for database-backed configs ...

This commit addresses multiple issues with schedule management and updates
  documentation to reflect the transition from YAML-based to database-backed
  configuration system.

  **Documentation Updates:**
  - Update DEPLOYMENT.md to remove all references to YAML config files
  - Document that all configurations are now stored in SQLite database
  - Update API examples to use config IDs instead of YAML filenames
  - Remove configs directory from backup/restore procedures
  - Update volume management section to reflect database-only storage

  **Cron Expression Handling:**
  - Add comprehensive documentation for APScheduler cron format conversion
  - Document that from_crontab() accepts standard format (Sunday=0) and converts automatically
  - Add validate_cron_expression() helper method with detailed error messages
  - Include helpful hints for day-of-week field errors in validation
  - Fix all deprecated datetime.utcnow() calls, replace with datetime.now(timezone.utc)

  **Timezone-Aware DateTime Fixes:**
  - Fix "can't subtract offset-naive and offset-aware datetimes" error
  - Add timezone awareness to croniter.get_next() return values
  - Make _get_relative_time() defensive to handle both naive and aware datetimes
  - Ensure all datetime comparisons use timezone-aware objects

  **Schedule Edit UI Fixes:**
  - Fix JavaScript error "Cannot set properties of null (setting 'value')"
  - Change reference from non-existent 'config-id' to correct 'config-file' element
  - Add config_name field to schedule API responses for better UX
  - Eagerly load Schedule.config relationship using joinedload()
  - Fix AttributeError: use schedule.config.title instead of .name
  - Display config title and ID in schedule edit form

  **Technical Details:**
  - app/web/services/schedule_service.py: 6 datetime.utcnow() fixes, validation enhancements
  - app/web/services/scheduler_service.py: Documentation, validation, timezone fixes
  - app/web/templates/schedule_edit.html: JavaScript element reference fix
  - docs/DEPLOYMENT.md: Complete rewrite of config management sections

  Fixes scheduling for Sunday at midnight (cron: 0 0 * * 0)
  Fixes schedule edit page JavaScript errors
  Improves user experience with config title display
